【问题描述】：
我有一个源模型脚本，当我尝试复制时，它似乎无法正常工作。谁能告诉我哪里出错了？
HTML（这只是说明表格应该放在哪里，并且 JS 脚本在最后，所以完整的 HTML 在运行脚本之前运行，所以我认为这里没有任何问题）：
<!DOCTYPE html>
<html>
<head>
<title>Weather App</title>
<meta charset="UTF-8">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>
<link rel="stylesheet" type="text/css" href="styles.css">
</head>
<body>
<header>
<h1>'>Weather App</h1>
</header>
<section>
<table id="weather"></table>
<div id="info"></div>
</section>
<footer>
</footer>
<script src="weather.js" type="text/javascript"></script>
</body>
</html>
JavaScript（我很确定问题就在这里，但我不知道为什么。我知道问题可能出在表格格式的响应部分，但我对如何以及为什么感到困惑):
(function updateWeather()) {
setTimeout(function() {
$.ajax({
url: "weather.json",
type: "GET",
dataType: "json",
success: function(response) {
let sTxt = "";
$("#weather").html("");
$.each(response.cities, function(index) {
sTxt += "<tr class='weather'><td>" + response.cities[index].cityName +
"</td><td>" + response.cities[index].currentConditions +
"</td><td>" + response.cities[index].temperature + "</td><td>" +
response.cities[index].windSpeed + "</td><td>" + response.cities[
index].windDirection + "</td><td>" + response.cities[index].windChillFactor +
"</td>" + "</td><td></td><td></td></tr>";;
})
$("#weather").append(sTxt);
updateWeather();
},
error: function() {
$("#info").html("<p>An error has occured</p>");)
});
}, 250);
})();
JSON（我不认为这里有什么问题）：
{
"cities": [
{
"cityID": "1",
"cityName": "London",
"currentConditions": "Warm and Windy",
"temperature": "28",
"windSpeed": "12",

感谢您的任何建议。
【问题讨论】：
-
您的字符串连接中似乎有一个额外的结束标签
</td>。添加response.cities[index].windChillFactor后，您有两个结束标签。你在同一个语句中还有一个额外的分号:) -
正如@khuynh 所说，在
index].windDirection +...之后确实有一个额外的结束。你到底看到了什么？ -
@seesharper 好吧，我只能看到 HTML 页面的标题，没有表格。我删除了多余的分号和多余的 ，但它并没有改变输出。
